Everytime I either, create an account on the Pretendo website and log in onto the 3DS, or try and create an account directly on the 3DS, I cannot get my 3DS on the Pretendo network. I have followed every step of the guide, Including configuring Luma3DS (Latest Release), and installing and setting the account type to Pretendo on Nimbus (Latest Release).
I unfortunately do not remember the error code that showed up whenever I tried to sign up on the 3DS, but the description was something along the lines of "HTTP Content Invalid". Does running the 3DS off of a metered connection cause this? Because I've been using my mobile hotspot for all of this and it had been stable during the whole setup process.
